Tornadoes aren’t just dangerous because of their sheer power: they’re also extremely difficult to predict. On average, weather monitors give us only 13 minutes’ notice to take cover. But mechanical engineer Jamey Jacob from Oklahoma State University hopes to extend the warning time to an hour or more. He and his team are developing rugged drones that can collect data from these violent storms.
